In a note sent out after Friday morning's broadcast, new ABC News President James Goldston called Spencer "as talented as they come" and a "key member" of GMA's on-air team. "Lara is clearly an essential ingredient in the success we have enjoyed and I am so pleased to announce that Lara has been elevated to co-host of the program along with Robin and George," he wrote.

Stephanopolous tweeted about the big news on Friday. "Huge congrats to my GMA co-anchor and friend Lara Spencer on her promotion!" he wrote.

Spencer has served as Good Morning America's lifestyle anchor since rejoining ABC in 2011. She was previously a national correspondent for the morning show from 1999 to 2003.
